Install Apache on Debian VPS & unmet dependencies error

I have a VPS and it runs on Debian GNU/Linux 8 (jessie). I try to install Apache, PHP, and MySQL on it. I get the below error:
The following packages have unmet dependencies:
mysql-server : Depends: mysql-server-5.5 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
When I run apt-get -f install, i get below error:

If are sure you want to downgrade to 5.5, remove the file
/var/lib/mysql/debian-*.flag and try installing again.

I have basic knowledge of Linux, so any suggestion or help. I search online and try to uninstall and remove and reinstall MySQL... but no luck.
from you error output i did a quick apt-cache search to see the version numbers of mysql-server
from what i seen you might have installed mariadb-server-10.0 installed instead of mysql-server
do a dpkg -l | grep mysql and look at the results. you could also try dpkg -l | grep server and look at that output also.
ADDED COMMENT-
did you remove the file that it's asking you to do?
if you need to have both db-servers running i would follow along with this
https://superuser.com/questions/1029228/mysql-and-mariadb-instances-on-the-same-server
if you don't need both dbs, then i would apt-get remove mariadb-.. from your server and then apt-get -f install to get mysql-server installed

A mysql client is installed, but when I try to launch it I get this:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Any help will be appreciated.
Well, I got no help from StackExchange, so I dug deeper and figured it out myself: First I got rid of mysql-server and mysql-client by following instructions at Removing MySQL 5.5 Completely. Then I simply installed the server and client as usual with apt-get. Everything worked fine after that.

dpkg: unrecoverable fatal error, aborting:
syntax error: unknown user 'mixmaster' in statoverride file
E: Sub-process /usr/bin/dpkg returned an error code (2)
Any ideas what I am doing wrong?
Try this
sudo apt-get remove --purge mixmaster
Or
Check for
cat /etc/groups.default | grep mix
If there is a mixmaster user/group in defaults put it in the system file too
edit /etc/groups and put in the put in the output of cat /etc/groups.default | grep mix command
run apt-get again
Or
Check for
dpkg-statoverride
This command may be of some help
